Broadband Forum: Broadband reaches 600 million subscribers worldwide
According to the Broadband Forum and analyst firm Point Topic, service providers worldwide added more than 16 million broadband subscribers during the first quarter of this year. The additions brought the total number of broadband subscribers worldwide to more than 600 million.“This is another significant milestone in an exciting arena that shows no sign of slowing down,” commented Robin Mersh, CEO of the Broadband Forum at the recent CommunicAsia event in Singapore. “It is just 18 months since we celebrated the 500 million subscriber watershed and even less time since IPTV subscribers reached 50 million -- yet in both cases growth is still accelerating. It is especially rewarding to be making this announcement in Asia, which has contributed so much to fuelling this phenomenal success. I am also particularly pleased to see how exceptionally well fiber is doing, a clear indication of the importance of our continued efforts in testing and certification of G-PON.”While DSL remains the most heavily used broadband technology – at 369,898,515, it accounts for more than half of current broadband subscriber lines – fiber-based technologies grew most strongly, the Broadband Forum and Point Topic report. FTTx subscribers grew 32.21% year over year, while FTTH line totals increased by 24.03% over the same period. DSL grew 7.52% while cable modem lines (the second most popular access technology) grew 8.48%.Still, FTTx and FTTH have a ways to go before they threaten DSL’s position, or even cable modem’s. FTTx lines stood at 87,732,35 by the end of the quarter, with FTTH lines at 16,519,984.“DSL is the most popular access technology on a global basis: Although its market share has dropped by 0.5% in the quarter, there is a long way to go before the copper-based access technology is overtaken,” confirmed Oliver Johnson, CEO of Point Topic. “For fiber, the cost-effectiveness, from the operators point of view, and the significant increase in bandwidth over DSL in particular is hitting the sweet spot at the moment in terms of technology market share.”

ASSIA DSL Expresse upgrade aims at 100 Mbps
DSL software tool vendor ASSIA, Inc. has released the latest version of its flagship product, DSL Expresse. The new ASSIA DSL Expresse 2.7 package extends the tool’s diagnostic capabilities, extends its use to multi-tenant applications, and improves its use as an operational tool – all with an eye toward supporting the wide deployment of 100-Mbps services via vectored VDSL.For example, ASSIA asserts that DSL Expresse 2.7 is the first product to offer advanced network management software for multi-tenant environments. The software enables multiple service providers to use the same software instance simultaneously to optimize their lines’ interplay and performance. This feature provides several benefits, ASSIA asserts:improves economies of scale in highly compartmentalized ISPs, as seen particularly in China and other regions in Asia accelerated ISP VDSL ployment through management coordination of co-existing copper pairs in preparation for vectoring the ability to share infrastructure costs among ISPs looking to introduce new services the ability to add a regulatory “super-user” to monitor the quality and performance of the network.Additional features in ASSIA DSL Expresse 2.7 include: Real-time line optimization Support for single-ended loop test (SELT) for enhanced diagnostics, cost savings, and service delivery, such as the ability to pinpoint faults and direct dispatches to their exact location Time-variable trend detection for lines that experience sporadic, random problems“The new features in ASSIA DSL Expresse 2.7 address many of the challenges that I’ve heard operators are having with VDSL deployments, such as microfilter detection and diagnostic accuracy,” said Jeff Heynen, directing analyst, broadband access and video, at research firm Infonetics. “Clearly, ASSIA is paying attention and has designed the latest version of its powerful, vendor-neutral DSL Expresse solution to help make VDSL rollouts cheaper, smoother, and faster. Real-time optimization, improved diagnostics, and multi-tenancy support all add up to faster broadband over copper and reduced time to revenue for operators.”

Avago Technologies offers 120 Gbps parallel optics in CXP, MiniPOD formats
Avago Technologies (NASDAQ: AVGO) has announced production of pair of products designed to support 120 Gbps multichannel parallel optic applications. The products include the AFBR-81uVxyZ and AFBR-82uVxyZ transmitter and receiver MiniPOD modules for “inside-the-box” data center applications and the AFBR-83PDZ CXP pluggable transceiver.The MiniPOD modules are an outgrowth of Avago’s successful MicroPOD products. Both the transmit and receive modules support 12 unidirectional channels, each of which can accommodate 10.3125 Gbps via 64b/66b encoding. They are compatible with MegArray interface specifications. According to Sharon Hall, product line manager at Avago, the modules should see application for proprietary intra-chassis links, mid-plane, and backplane designs. The MiniPOD approach 36 times the density of designs based on standard SFP+ optical transceiver modules, she adds.The MiniPOD modules are available in two package options to support either flat ribbon or round fiber jumper cables.Both the MiniPOD modules and CXP transceiver can transmit data up to 100 m over OM3 fiber and up to 150 m over OM4. They are compliant to 802.2ba 100-Gigabit Ethernet specifications (100GBase-SR10 and nPPI) as well as the QDR Infiniband standard. They are based on Avago’s VCSEL laser arrays operating at 850 nm for the transmitters and the company’s PIN diode array for the receivers.An evaluation board for the MiniPOD modules (AFBR-800EVK) is available at a single-unit price of $2500 each. In 100-unit sample quantities, the AFBR-81uVxyZ transmitter module and AFBR-82uVxyZ receiver modules sell for $649 per transmit/receive pair. An evaluation board (AFBR-83EVK) is available for the AFBR-83PDZ CXP pluggable transceiver at a single-unit price of $3500. The module itself sells for $749, also in 100-unit sample quantities.
